Specifically manufactured from high-grade stainless steel to deliver superior structural longevity, outstanding corrosion resistance, and a striking high-end finish, this kit perfectly fits the popular VN to VS Commodore series and VQ to VS Statesman luxury platforms. By completely replacing the highly restrictive factory cast iron manifolds, it dramatically lowers backpressure, optimizes exhaust gas scavenging velocity, and provides an aggressive, crisp V8 tone.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"feature-block\"\u003e\n\u003cdiv class=\"feature-content pb-6\"\u003e\n\u003ch3 style=\"color: #e60000; font-weight: bold;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003ePRODUCT CONTENTS:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Premium Stainless Steel Performance Exhaust Extractor Header Set (Left \u0026amp; Right Bank Assembly)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-grade stainless steel construction provides maximum defense against under-car atmospheric moisture rust, extreme gas scaling, and harsh environmental oxidation\u003c\/li\u003e\n\u003cli\u003eTuned mandrel-bent primary piping pathways map perfectly to high-port symmetrical VN-style EFI cylinder heads, ensuring completely uniform gas flow routing and maximizing engine efficiency\u003c\/li\u003e\n\u003cli\u003eSubstantially optimizes low-to-mid range torque delivery and throttle response—perfect for high-performance street cruisers, heavy towing setups, and customized show cars\u003c\/li\u003e\n\u003cli\u003eThick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against face distortion, thermal warping, and exhaust gas leaks\u003c\/li\u003e\n\u003cli\u003eEngineered as a direct bolt-on replacement path designed to drop down safely past standard K-frames and automatic\/manual transmission tunnels cleanly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cdiv class=\"specs\"\u003e\n\u003cul class=\"flex flex-col space-y-2 text-xs\"\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eBrand:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eAdvance Headers\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003ePart Number:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eA314SS\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eMaterial:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eHigh-Grade Stainless Steel\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eEngine Suitability:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eHolden 5.0L 304ci EFI Pushrod V8 Petrol Only (Not for early 253\/308 blocks)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eSteering Rack Compatibility:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eStandard Power Steering \/ Manual Racks Only\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eTransmission Limitations:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eFits 5-Speed Manual \u0026amp; 4-Speed Automatic (Will NOT fit 6-Speed Manual)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eComponent Type:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003ePremium Performance Exhaust Extractors \/ Headers\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eEstimated Fitting Time:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003e2.5 Hours\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eWelding Required:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eNo (Direct Bolt-On Configuration)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003e⚠️ Crucial Component Restrictions \u0026amp; Modification Warnings:\u003c\/strong\u003e\u003cbr\u003e1. \u003cstrong\u003e6-Speed Manual Exclusion:\u003c\/strong\u003e This extractor assembly will \u003cstrong\u003eSTRICTLY NOT FIT models fitted with a 6-speed manual transmission\u003c\/strong\u003e due to substantial clearance constraints caused by the wider casing boundaries of that specific manual gearbox configuration.\u003cbr\u003e2. \u003cstrong\u003eVariable Speed Steering Rack \u0026amp; Knock Sensor Restrictions:\u003c\/strong\u003e This standard design does \u003cstrong\u003eNOT clear vehicles running a factory variable-speed\/variatronic power steering rack\u003c\/strong\u003e (requires alternative Part No. \u003cstrong\u003eA314V\u003c\/strong\u003e).
